Aresearcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. remarkably, she notices that this signal results in an increase in eukaryotic gene expression. how is this possible?

This is an incomplete question.

Below should be the complete one with options:

A researcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. Remarkably, she notices that this signal results in an increase in eukaryotic gene expression. How is this possible?

A.This gene expression is likely independent of the presence of the prokaryotic signal.

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

C.This signaling pathway might actually be utilized by both prokaryotes and eukaryotes.

D.This signal is likely similar in structure to ligands utilized by eukaryotic cells.

E.This prokaryotic signal likely travels directly into eukaryotic cells and acts as a transcription factor.

THE CORRECT ANSWER IS B

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

Explanation:

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
